Hey I'm 11+3 and been having morning sickness since 6 weeks constantly and it seems to feel worse when I'm drinking water.it cud be coz I hate the taste of it anyway but I'm only drinking about 750ml a day and have to put black currant into it to make it tolerable.on my little boy I was able to drink nearly two litres and am feeling guilty for not drinking that amount this time.i drink a lot of milk though
